Question

Compare 3 over 4 minus 3 over 8.

  1. <
  2. >
  3. =
  4. not equal to

hintHint:

1. When we compare 2 fraction, we check which one of the 2 is larger and which one is smaller and accordingly, assign the appropriate inequality sign i.e. greater than > or less than < to the 2 fractions.
2. If the denominators of the 2 fractions are different, we find the LCM of the denominator and multiply the denominators to make them equal to the LCM and then compare the numerators.

The correct answer is: >


GIVEN-
Fraction 1 = 3/4
Fraction 2 = 3/8
TO FIND-
Comparison between the 2 fractions.
SOLUTION-
From the given information, we observe that-
The denominators of both the fractions are different i.e. 4 & 8.
Hence, find the LCM of 4 & 8 i.e. 8.
We make the denominators equal to 8 as-
Fraction 1 = 3/4 = 3*2 / 4*2 = 6/8 ............................................. (Multiplying numerator and denominator by 2)
Fraction 2 = 3/8
Now, the denominators are same, we compare the numerators as-
      6 > 3
∴ 6/8 > 3/8
∴ 3/4 > 3/8
FINAL ANSWER-
Option 'b' i.e. '>' is the correct answer to the given question.
